Use of SPT and CPT Tests for Evaluating the Liquefaction Resistance of Sands
A cone penetration test (CPT)-liquefaction resistance relationship has been established using the large body of standard penetration test (SPT) data. Factors for relating CPT tip resistance...
Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
Pressuremeter Tests and Shoring Wall Design
Pressuremeter testing was used as an integral part in the design of the temporary tieback shoring wall for the Columbia Center office building in Seattle, Washington. Pressuremeter testing...
Probabilistic Study of SPT Liquefaction Analysis
The influence of earthquake magnitude upon the commonly used correlation between Standard Penetration Test (SPT) blow count and liquefaction potential is evaluated using a probabilistic...
Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...

This paper presents a tentative method for evaluating the limiting skin friction f//s for piles driven in clay based on sigma //h'c (horizontal effective stress at the interface...
Determining Sand Strength by Cone Penetrometer
Evaluation has been made of several theories and methods for deducing sand strength from cone resistance. Bearing capacity theories, cavity expansion theory, and empirical methods have...
Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...
Site Characterization Using the Cone Penetrometer Test
The Cone Penetrometer Test (CPT) when used in conjunction with a limited soil boring program can provide a more detailed and economical site characterization. This paper addresses how...
In-Situ Testing to Characterize Electric Transmission Line Routes
A review of the literature has shown few definitive studies which separate test variability from soil inhomogeneity. A sensitivity study was performed to evaluate the effects of the overall...
Soil Improvement Evaluation by CPT for Tanks
Trial soil improvement by gravel compaction piles and dynamic consolidation, and a subsequent full-scale loading test on loose volcanic ash soil were conducted prior to the design of large...
Effect of Cementation on the Cone Penetration Resistance of Sand
A laboratory study was conducted to investigate the effect of cementation on the cone penetration resistance of sand. A new apparatus to form homogeneous artificially cemented sand specimens...
Design Parameters for Grouted Piles in Rock From In-Situ Load Tests
A series of pile load tests were performed at an onshore site to develop final geotechnical parameters for the Gaviota platform foundation which consists of large diameter drilled and...
